F lRE-PROOF CEILING.

SPECIFICATION forming" part of Letters Patent No. 272,658, dated February 20, 1883.

. Application filed June 6,1882. (No model.)

tire-proof ceiling that is suspended in a simple and reliable manner from the wooden beams of the building, so as to protect the same in an efficient manner against tire; and the invention consists of plates of fire-proof material which are suspended from the beams by metallic bands or wires that are attached to the beams and to perforated lugs at the upper surface of the plates.

In the accompanying drawings, Figure 1 represents a perspective view of my improved file-proof ceiling. Fig. 2 is an end view of the same, and Fig. 3 a simpler form in which my fire-proof ceiling may be suspended from the beams.

Silu'llal letters of reference indicate corresponding parts.

A in the drawings represents the wooden floor-beams, which are to be protected against fire by a fire-proof ceiling formed of plates B B,ot'fire-clayorotherfire-prootmaterial. These plates are suspended from the beams by means ofmetallicbandsorWiresO,ot'suitablestrength, said bands or wires being attached at their upper ends to the beams and at their lower ends to slitted or perforated projections or lugs 12, formed at the upper surface of the plates B. The bands are reliably secured to the slitted or perforated projections or lugs b, so that they cannot be detached therefrom, which may be accomplished either by turning over the ends of the bands, as shown in Fig. 3, or

40 by making the lugs b b of semicircular or U shape, and of a width equal to the beam, and passing then a continuous band or wire, 0,

through the same, as shown in Figs. 1 and 2.

ends being beveled, so as to form a dovetailed recess for the plaster. By suspending in this manner a series of fire-proof plates below the beams of a floor a shield is formed that protects the wooden beams against the action of fire below, while a convenient, cheap, and

easily-applied means is furnished, whereby warehouses, offices, and other buildings,whether in course of erection or already erected, can

be readily changed into fire-proof structures at a comparatively small expense.

Haring thusdescribed my inventiomlclaim as new and desire to secure by Letters Patent The combination of the wooden floor-beams with plates of fire-proof material which are suspended by metallic bands or wires at a suitable distance below the beams, said suspeu sion bands or wires being passed through slotted or perforated projections or lugs at the upper surface of the plates, substantially as set forth.

In testimony that I claim the foregoing as my invention I have signedmy name in presence of two subscribing witnesses.
